Abstract (en)
[origin: WO02090403A1] Disclosed are methods for advantageously producing maleated polypropylenes having a relatively high percentage of bound maleic anhydride, base on the total amount of maleic anhydride moieties present in the grafting reaction product, and the maleated polypropylenes produced therefrom. The methods produce maleated polypropylenes wherein at least about 60% of the maleic anhydride moeities in the grafting reaction product are bound to the polypropylene.
